About this file
This document contains a preventative maintenance checklist and related federal contract opportunity. The preventative maintenance checklist outlines routine inspection and maintenance procedures for various building systems including boilers, oil burners, furnaces, water heaters, pumps, and winterization of boiler systems. It specifies inspection frequencies and tasks for ensuring proper operation and identifying needed repairs.
The related federal contract opportunity is a solicitation seeking preventative maintenance and repair services for World War II-era and relocatable facilities at Joint Base Lewis-McChord in Washington. The solicitation is set aside for Service-Disabled Veteran-Owned Small Businesses and is seeking maintenance and repair of building mechanical systems, including those outlined in the preventative maintenance checklist. The combined synopsis/solicitation provides opportunity details but no response date or pricing terms.
